We have developed a new method for the integration of ion-sensitive membranes and silicon sensor chips. The ion-sensitive membrane is deposited in pyramidal containments produced on silicon by an anisotropic etching technique. Here we demonstrate the application of this method to the development of
Carbon paste electrodes were prepared by mtxmg graphite powder wtth hqmds that have been applied as plastrctxers for membranes of ion-selectrve electrodes In voltammetnc measurements, these electrodes exhrbtted mterestmg properties such as a wrde anodtc and cathodrc potentral range, very low reductr
The mechanism of ion selective electrode membranes based on valinomycin+KBPh, in plasticized PVC is discussed in the light of recent impedance studies. In a typical membrane the K + is largely present as K+val -BPh, ion pairs. The transport number for K+val is -0.87 whilst that for BPh4 is -0.13. At
